Beam slope across break

[Knute Snortum]

I am engraving a piece with a lot of beams crossing breaks.  Most of the
time LilyPond does fine with these, but once in a while I'd like to adjust
the beam slope of the second part of the broken beam.  Overriding beam
positions seems like a good fit here, but in my case it produces stems too
long on the second part of the beam.

I have attached a PNG displaying the behavior with the code that produced
it below.  The first score shows how the default beam positions after the
break don't look good, and the second shows my attempt to fix the situation.

In short, is there a way to control the slope of the beam after the break,
or some other way to deal with the situation?

\version "2.25.7"

\layout {
  indent = 0
  ragged-right = ##t
}

\relative {
  \time 6/8
  c'4.^"without override" a8[ e' a | \break
  g'8 c e,] c4. |
}

\relative {
  \time 6/8
  c'4.^"with override"
    \once \override Beam.positions = #'(-6.5 . -3.5)
    a8[ e' a | \break
  g'8 c e,] c4. |
}
